It is natural to assume that later versions of software will improve performance and fix bugs. However, you may run into the opposite if you try that with an Access 97 database and the Microsoft Data Access Components (MDAC) 2.1. According to Microsoft postings, Access 97 databases should only use the Jet 3.51 OLE DB provider. Don't use Jet 4.0 OLE DB. Apparently Jet 4.0 OLE DB has to go through a translation layer to talk to pre-Access 2000 databases and that introduces a host of problems Likewise, don't use the MDAC 2.1 version of the Access ODBC driver (via MSDASQL) to access Access 97 or earlier databases at this time. According to the MS technical support the version is hard-coded to use Jet 4.0 OLE DB.
